使用Ansible解析json

Question

我有一个如下的json：

    "instances": {
      "biometricsManagerInstance": {
        "appId": "biometrics-manager",
        "spawnType": "uniqueSiteWide"
       },
      "videoSensorInstance": {
        "appId": "video-sensor",
        "spawnType": "reuse"
      },
     "faceDetectionInstance":{  
        "appId": "face-detection",
        "spawnType": "reuse"
      },
     "faceMatchingInstance":{
       "appId": "face-matching",
       "spawnType": "new"
      },
      "faceAnnotatorInstance":{
        "appId": "face-annotator",
        "spawnType": "new"
       }
  }

我有一个存储json的变量。假设: my_json_contents我想用这个数据创建一个字典，它的值如下：

    {"biometrics-manager":"biometricsManagerInstance","video-sensor":"videoSensorInstance","face-detection":"faceDetectionInstance",..}

我想用ansible来实现它。Help是appreciated.TIA。

您的位置如下：

- set_fact:
    instances_modified: "{{ instances_modified | default({}) | combine({item.1.appId: item.0}) }}"
  loop: "{{ instances | dictsort }}"
